Y., A CORPORATION OF N EW YORK MACHINE FOR AEPLYING STRPS TO BOOKS Original application filed December 31, 1928, Seria1 No. 329,466. Divided and this application filed March 7; 1326, Serial No. 5,579. Renewed September l, 1931.

This invention is a novel machine for ap-y the backs of signature groups in the process of being made into round baci; books, although the invention is ot utilty for attaching analogous strips to various types of books. Tirs application is a division of December 3i, i928.

ylfhe present invention is an accessory and an improvement to be used in connection with a book-binding machine such as is illustrated and described in th-e patent to B. Gitzenoanner, numbered LSSOQQei entitled Boolabinding machine, and also adapted for use upon numerous other boolrbinding machines described in other patents and now in general use.

The book-binding process upon such machines is now substantially a continuous operation. A plurality of signatures are picked up by carriers, generally over thirty in number, and conveyed as a group along a predetermined path ot travel past a number ot successive instruin-entalities whereby a fabric lining, a paper lining, and ot ier elements which are employed for the purpose ot maintaining the sgnatures in bound relation are applied.

The present invention is substituted tor the conventional paper strip or back-lining attaching device, and adds to the paper strip baclr'ing apparatus means for the attachment of headbands to the paper backing nd to the group signet if lt also ion of headbands to a group ot signatures, for the device automatically' brings together the paper stripE the headbands, and the cord which is inserted into and comprfses a ii-art et the heanba The present apparatus permits of the aplication of the 'readbands to the paper strip `helling with t I ne preferred method ot ausing adherence,y and does not in any Way sloiv up or interi-ere with the operation oi the book-binding machine or with its eiiiciency as applied to any other operation which it is called upon to perform.

A book-binding machine is shown generally, it being suliicient to state that the device hereinafter described is shown at a station upon the endless path or track of the bookbinding machine. A plurality oi carriers or clamps Within each of which a group of signatures is firmly held are arranged upon such traclr, the signatures always being disposed With one vertical edge. contacting upon a peg or pin so that the position of the group oil signatures in each of the series of carriers is always the same. The carriers are moved about upon the track. Because ot the great Weight of the machinery, it has been impossileto devise a. means whereby each carrier registers in the precise position of its predecessors when the machine is stopped as is required for its operation at the dierent stations for the application of linen and paper linings, and for the additional operations required.

One of the greatest ditliculties in procuring the proper attachment of a headband to a group ot' signatures in a machine ot the character herein referred to is the impossibility, heretofore, of registering each carrier in exactly the same position which its predecessors occupied, With the result that any device intend-ed to apply headbands to the bool; in process ot binding has affixed such headband in an irregular manner or varying position upon the book back.

instead of endeavoring to cause each carrier to stop in a predetermined position for reoistry With the device applying the headband, the present invention comprises means for attixing the headbands to a Web oi" paper lining and then registering the paper lining to which the head-.bands are attached in its poper relation upon the partly bound group or signatures. The registration occurs subsequent to the time when the headbands are secured by glue to the paper lining Web, so that the paper lining with the glue attached headbands thereon may be adhesively secured to the partly bound Group ot signatures by glue in the manner conventional in the art and c nsistent with the character of the machine here disclosed.

Such a` method has a distinct advantage Cal In the course of the attachment of the headbands to a group of signatures, the present apparatus contemplates the preattachment of the headbands tothe paper lining, the severing of the headbands so attached and a. portion of paper lining from a roll of such latter material and the manipulation of the severed portion until it correctly registers with a group of signatures whereupon it is affixed thereto.

All of these steps are accomplished through the agency of the herein described machine, which, as has already been stated, is an accessory device adaptedto made al part of the machine illustrated and described in the above referred to patent, and of other bookbinding machines. n

The objects of the invention, therefore, in-

"- clude forming a paper lining having headbands at its edges and affixed thereto with glue, and attaching such a paper liningr to a group of signatures, and correctly registering such-lining and its headbands with the end edges of the back of the group of signatures.

These objects and such other objects as may hereinafter appear, are obtained by the novel construction, combination and arrangement of the elements some of which of themselves are novel, shown in the accompanying sheets of drawings, hereby'made a part of this speciication, and in which one embodiment of the invention is disclosed.

In the drawings:

The present invention may be employed in association with other book binding machines than that illustrated in Figure 1 of the drawings, but such machine being typical of the high developments in the art, the present headbander has been applied thereto, and in this application forms a part of a device of the character and type illustrated in the patent to B. Gitzendanner, numbered 1,380,294, issued May 31, 1921, and entitled Book binding machine.

Figure 1 of the above referred to patent to Gitzendanner has been substantially reproduced as Figure 1 of the drawings in the present application, there being a few deletions, and there also being in addition to the machine there illustrated, and at the near side of Figure 1, the headbander forming the present invention which for convenience is ereinafter sometimes referred to as a back lining machine and also as a headbanding device.

Reference to Figure 1, in conjunction with reference to the patent to Gitzendanner, above referred to, discloses a book binding machine having a plurality of signature holding clamps 20, connected in train. While conveyed therein each signature group is trimmed, roughened, and grooved. Adhesive is applied thereto, a lining or super of open meshed cloth, attached, and in the present instance, next, headbands and a paper lining are affixed. Later a cover may .be applied, the cover broken, and a completely bound book delivered at a station adjacent to the position at which the group of signatures was originally received. Means are employed at the loading station to cause the signatures at one end to engage a stop or gauge member in the holding device so that all y a definitestationary position groups of signatures occupy the saine tive space in the clamp.

lVhile the machine is intended to bring anc-ther, into each of these clamps, ft

one a he stops or stations provided therefor, the J a variation, sometimes but sligln` ancL at other times highly appreciable, in the position at which each separate carrier or clamp comes to full stop at any of the stat-ions named. This uncertainty of the positA of rest increases or decreases With respect the speed at which the device is operated, the amountof Wear thereon, i. e. age of the device, a la, of course, with the dimensions and Weight of the group of signatures to be bound therein.

In each of the clamps or carriers, 20, there are sides 2l and 22, which may be called a front and a back. There is also a pin 29 v against which the group of signatures 2e contact. `Within the carrier 20. the group of signatures 24, as en lained above, always occupies the same relative iosition and if an operation With respect` to a group of signatures 2l is to be carried out, it is reasonable, feasible and proper to have such operation gauged With respect to the pin 23 uf'hich is secured to plate 22 and which projects through an opening in plate 2l in order t" an element, such as a crash or paper lining will register upon uch group of signatures 24 in direct relation to the position thereof with respect to saic1 transverse pin 23 and thus provide uniformity.

.Figure l discloses the association of a plurality of carriers 2O each comprising an outer plate 2l, an inner plate 22, and yoke 2b in association with two transverse bolts 2?. Said bolts are surrounded by coil springs 28, one end of each of which is adapted to bear against the inner face of said yoke 25 and tno other end to rest against said inner plate 22, said latter plate beingfirmly anchored upon pivot stud' 29 traveling in a f d of opposed l-shaped members 3l.

An adhesive applying device of the usual character may be employed upon the machine as modified, and there is no necessity for supplying such a mechanism of special character.

As is usual in book binding, there is an arrangement called and marked strip attaching for securing of pervious material or fabric lining to the book, this material comprising a length of crash or other Widely meshed tough Woven material which is affixed to the back of the group of signatures 2e after glue has been spread over the ack edge of the group of signatures.

Reference should nov? be had to the headbanding device hereinabove so frequently referred to. Suitahly attached to a base 3; Within the book binding machine and separated one from another are vertical frame members .or standards 33, suitably oined toofeee 3 gether. All of the mechanism hereafter described as forming a part of the headbanding device depends upon and/or is between said frame members 33. Said frame members 33 project outwardly from tie base 32 of the book binding machine and beneath the track provide mountings for brackets and reservoirs.

Tivo brackets 35 are provided and are spaced apart, one upon each frame member 33, and these each terminate in an open ended U-shaped bearing 36, in Wl lch a shaft or core 37 for a roll 38 of strip material., generally paper, is disposed for free rotation. Also upon said brackets 35 and journalled therein is a shaft 39 to Which adjustably secured guide roller 4() one at each end of shaft 39 between which and over shaft 39 the stripv of material passes on its journey from the roll 38.

Paper Webs for back linings usually comes in rolls of many yards in length. There are several Widths for such paper rolls but t is eldom that a standard Width of paper s the correct size for a particular bookbindne 0b.

ing] To prepare in advance a great number of Wir the of paper would he impractlcable both for the manufacturer of the paper and also for the bookbinder both of Whom would have a large amount of money tied up in the many sizes required. From handling, too, the paper While in roll develops irregular edges due to blows on itsilat sides, so that a few standard Widths of paper are provided and these are trimmed to size in the bookbinding machine during the binding operation. Guide rollers l0 are provided to main tain the jnment of the paper strip as it advances toward slitters or cutters.

ln the present instance, the cutters are mounted upon shafts ell and Ll2 ournalled in brackets 35, and upon each of said shafts 41 and 42 are circular lives, cutters or slitters i3 Which may be disposed on said shafts in any selected position and firmly attached whereby the paper web taken from roll 38 is trimmed to size and sharply defined edges are obtained thereon While passing intermediate the shafts ll and 42.

A. second series of guide rollers de are adjustably disposed upon a shaft l5 also journalled in brackets ano the paper passing around said shaft 45 and between said rollers le one of Which is adjacent each end of said shaft 45 changes its direction of movement from the substantially horizontal to vertical direction.

Brackets 35 are secured to the outer end and under side of standards 33 by any suitable fastening means, as per example the machine bolts t6 shown in Figure 2 of the draW- ings.

Pivoted to the tank 47, at one side thereof and at opposite ends, are two arms 48, the pivotal supports therefor being marked 49.

Upon the inner end of arm 48 is a reduced section 50. In association therewith is a thumb screw 51 which is also associated with a mixed member 52 whereby rotation of screw l raises or lowers the opposite ends of arms 48, the rotation being about pivot 49, to raise or lower a glue roller 53 riding on a shaft 54 journalled in arms 48 in respect to the level of glue in pot or tank 47. The amount of glue picked up by roller 53 is thus accurately regulated.

Adjacent the reduced section of arms 48 a roller 55 is journalled. Such roller is of greater width than the paper web and forms a guide therefor to insure the application of glue to the edges of such paper from a pair of glue-carrying rollers 56 which are adjustably mounted upon a shaft 57 journalled in one end of links 58 which have their other ends pivotally supported about roller 55.

Rollers 56 contact roller 53 and take glue therefrom and transfer a sufficient quantity thereof to the edge of the paper taken from roll 68 as such paper travels vertically7 from ,guide rollers 44 to the station where it is joined to the headband material. Some short space of time elapses between the application of the adhesive to the edges of the paper and the application of the headbanding strip thereto, and likewise an added period of time intervenes before the combined bands and strip are aiiixed to the group of signatures 24. This allows adequate time for the glue to bij contact between the paper and rellers because the paper is drawn upwardly at an angle formed about said glue carrying rollers 56.

Upon the other side of tank 47 and which tank forms a support therefor is a second pair of brackets 63 projecting upwardly and forming ournals for a number of shafts and rollers, and also supporting a second tank in which water is generally stored. Extending from the brackets 63 is a second pair of brackets 64 which provide holders for two balls of twine 65 andtwo rolls of headbanding material 66. It is, of course, understood that lieadbands are affixed at opposite ends of the book, and are oppositely disposed structurally with respect to such book.

From each ball of twine 65, twine 67 is unwound through suitable means for preventing an accumulation of slack, but not offering excessive resistance to the unwinding of the end 67 from the ball 65. These members, comprising ay guide means 68 at 0p posite ends of a horizontal member 69, and

an intermediate grooved roller 70 may be disposed upon a pivoted support 71 ufpon a standard 72 as is shown, such standar 72 being supported from a lug 73 projectin from the base 74 upon which theball o twine 65 is disposed. Horizontal member 69 is angularly adjustable upon standard 72 because of the pivotal support 71 therefor and thus may be used` to compensate for different widths of paper used in the device.

The twine 67 is caused to travel downwardly and about a grooved pulley 75 from whence its travel is upwardly and around a guide pulley for the headband material, the twine being caused by grooved pulley 75 to be guided to the center of such material which is later folded over with the twine 67 in the folded over edge section. Said pulley is journalled in brackets 64 which brackets extend to the left of Figure 2 to concurrently support a standard 7 6 which supports twine ball base 74 and the spool of headband material in the form of a tape or strip as will be described.

As previously stated, there are two spools of headband material 66 which are secured in` an adjustable position upon a shaft 77 which is journalled in brackets 64.

In the present apparatus these spools 66 may be disposed to align with the cord 67 after it is unwound from spools 65. Suitable brake and guide means, such as the members 7 6EL at the opposite side of the spools 66, are arranged to prevent a too rapid unwinding of the material and to keep said material from side-slipping.

The headband material generally referred to herein is now made in narrow strips. This material, except silk headbands, later to be mentioned, is made of cloth with an inner unfinished surface to which an adhesive has been applied and then dried. After the adhesive has dried, the material is rolled into spools; The present machine takes such strips from spools, meistens the inner surface, applies a cord to the center of the moist strip, folds the strip so that its two edges abut and its finished surface only is exposed and keeps the cord confined within the folded edge.

In this machine, when not using the cord parts and the strip moistening and folding parts, a Vsilk headband which comprises a preformed single thickness of material having one corded edge, may be fed directly from its spool to the point where the paper lining and headband are joined, and where such silk headband may be united with glue to such paper web preliminarily to attachment to the group of signatures 24.

The spools of headband material are unwound from underneath, and are drawn over and about a plurality of rollers beneath the smaller water pot heretofore referred to and numbered 78. In .its travel, it passes over .guide rollers 7 9 adjustably secured to shaft 80 journalled'in bracket 68, and under guide rollers 81, secured to a shaft 82 journalled 'at the opposite of .said water pot 78.

Above the water pot 78 is .a shaft 83 also journalled in brackets 63 upon which are water carrying rollers 84 which are adapted to ride in said water reservoir so that the inner side of the headbanding material becomesthoroughly moistened with water to reestablish the adhesiveness of the glue coating thereon. v

From rollers 84 about which the material travels about a quarter turn, the moistened material passes to a pulley or ianged roller 85 adj-ustably secured to a shaft 86 also journalled in brackets 63. This roller is in juxtaposition to pulley 75 and as the material of the headband travels about pul-ley 85, the cord 67 is being made to adhere to the center of said strip.

rAlso depending from brackets 68 is a vertical standard 87 having at its top a holding member 88 adjustably secured to said standard by a thumb screw 89. From holder l88 depends an arm 90 having a bifurcated end through which the cord 67 now riding on the` adhesive surface of the headband strip must pass. Such arm 90 extends into .a chute or guide 91 for folding one half of the headband material longitudinally over the other half, such member 91 being secured by fastening member 92'intermediate brack- .ets Such folding means comprises a cons ventional folding chute whereby one half of a flat strip of paper or the like is twisted over until it lays flat upon the other half of the strip with the edges of both sections in parallelism.

In the chute 91 is a roller 95 disposed on a fixed vert-ical stud 96 and in juxtaposition thereto is a roller 97 carried by an arm 98 l journalled on another vertical stud 99 disposed at a point in saw chute 91 below stud 96. The strip as it approaches rollers 95 and 97 at its center and about the cord 67 is held down by the bifurcated member 90 while the edges of the strip are twisted upwardly until joined one to another as they pass between rollers 95 and 97.

In the present instance. the folded strip with the cord within the folded edge passes to rollers 95 and 97, to rollers 100 adj ustably disposed upon a shaft 101 j'ournalled in the end of bracket and inV juxtapositionV to rolier 59. Said rollers 100 comprise a grooved section for the thickened end of the folded headband and for the corded side of a Asilk ieadband when used) and thus guides the assembled head evenly in the direction of the book binding device.

Above the roller 59, is a shaft 102 journalled in links 103, such links being rigidly secured to a shaft 104 journalled in arms 105 extending upwardly from bracket 60.

A lever 106 is secured to shaft 104- by means of a spring 107 the tension of which is adjustable at the will of the operator by a thumb screw 108, rollers 109 on shaft 102 and having tracked `portions to ailow for the varying thicknesses of the headband in transverse section, are forced into resilient engagement with the headband material and paper strip as it passes over roller 59 to secure an adhesive binder therebetween. One side only of the folded headband is secured to the paper and the corded edge projects a pre determi-ned -distance there beyond.

A .series of spaced apart driver rollers 110 is disposed upc-n a shaft 111 ournalled above and in lugs upon horizontal bed 61 and therebeneath is an idler 112, generally knuried to insure positive movements of the paper, between rollers 110 and idler 112. Suitable gearing (not shown) is provided to drive shaft 111, such gearing providing for the intermittent movement of said shaft to advance the paper between rollers 110 and idler 112 a predetermined distance when the machine is in the position shown in the fuil lines of Figure 2. Any suitable gearing by which the proper synchronism is obtained will serve for this purpose, and for this reason it is thought unnecessary to detail the speciiic gearing, generally of the chain type, which is required therefor. Such gearing is vdriven by the same prime mover by which the main book binding machine is driven which facilitates the necessary synchronism of the movement of the headbander with the remainder of t-he book binding devices.

As already noted, the associated strip and headband pass over `the horizontal bed or platform 61. At the end of the platform 61 and secured to said platform by end members 113 is a flat knife 114 which spans the paper and headband that pass thereunder.

Normally disposed beyond at the end of said platform 61 and when at rest with its top in the same horizontal plane as that of the platform 61 is the knife 115 which consti-'tutes a top member of the movable apparatus comprising the main features of the present invention. This apparatus comprises a main body 116, having at its top the bar knife 115 secured thereto by screws 117 and having eX- tending therefrom lugs 118 which narrow to provide tongues 119 to ride in a groove track 120 formed in the fixed body associated with the apparatus disposed on standards 38 and of which bed 61, is the top, the course of movement of the movable member relative to the lined portion associated therewith being upward in the direction of the group of signatures 24 toV which the associated lining and headband are to be affixed and to which a section thereof is affixed, and then a return to pick up an additional section of such material.

This motion or movement is made only when the main book binding apparatus is stationary, so that the action of the prime mover may be so arranged by cams orrotherwise to actuate first one and then the other in the order required.

In the apparatus, a cam 121 shown in Figure 2, is carried on a driven shaft 122 and is adapted to actuate a lever 123 pivoted at 124 upon the standard 33 supporting theA device to lift the movable body 116 during such periods of time as the main book binding apparatus or the carriers are stationary. As the cam 121 rotates with the shaft 122, its periphery engages a roller 125 at one end of the lever 123, causing the lever to move on its pivot 124 whereby to cause the opposite end of the lever to risey such o osite end being connected by a link 126 which is pivotally connected to the main body member 116. The main body member 116 is thus made to rise in a vertical direction until the top surface of the knife 115 comes in contact with a group of signatures 24. To insure a prompt and a smooth return of body members 115 as the cam 121 changes its position with the rotation of shaft 122 with respect to the inner end of the lever 123, there is provided a spring y127, one end of which is aiiixed by hook and eye or otherwise to said main member 116, the other end thereof being secured to a U-bolt 123 anchored .to a lug 129K extending from the frame 32 of the book binding machine. f f v The said main body member 116 may comprise a shell or itmay be hollowed out Aby tooling, there being at the top thereof, a rectangular opening extending almost from end to end which is covered at its top by the knife 115 and by a plate 130 in which there is a plurality of openings, 129, generally rectangular, the purpose of which will shortly appear. Said main member 116 in its vertical movement upwardly and downwardly must maintain air connections with members which are stationary. Coincidentally with its initial upward movement, it is adapted to cut off a predetermined amount of the paper strip with the headband material at its sides, the desired section being severed by the intersection of knives 114 and 115, these sections to be carried upwardly one at a time to be joined to or attached to the group ofy signatures 24.

Such cuttinr off is obtained by close interft of the two rknives, one 114 being attached to and bridging said platform 61' with its cutting edge thereabove, and the other forming the outer and upper edge of said member 116. Thus, as an incident to the rise moved .being regulated bythe movement of the feed rollers 110 upon shaft 111.

During the interval of time while said main member 116 is at rest and in juxtaposition to said bed 61, the gears associated with shaft 111, hereinabove referred to, are actuated and advance the lining and associated headbands overy the ytop surface of the knife 115 on said main member ready to be cut off for the next group of signatures to beapproached. lf desired, the top of said main member v116 may comprise only Va knife 115y and itmay be in the knife 115 that the rectangular openings 129 hereinabove referred to are formed.` f

' Cut olf sections of linings with headbands are shown in Figures' and 8. The parts thereof are lettered to show the paper section, lwhich ismarked paper, the cloth section whichis marked cloth, and one figure is partly broken away to show the cord center, marked cord. .f

Extending through said main member 116 are end openings 131 to receive a sliding rod 132. Said sliding 'rod 132 has at one endia collar, 133, firmly secured thereto, and intermediate said collar and the adjacent end of said main mei iber 116 is a coil spring 134 encircling said rod 132 whereby to urge it in a right hand position with respect to Figure 3.

At its other end, said rod 132 has associated therewith a yoke or bracket,'135, firmly secured thereto, and which in the present instancein normal 'position extends upwardly and above the main member 116. At its top, said yoke 135 has meansfor journallingI a shaft 136 and upon said shaft is a roller bearing 137, said bearing being adapted to engage the outermost plate 21 of said signature holder 20 as each one of such holders is at rest above the main member 116 and while said main member 116 is rising under the influence of the cam actuated lever 123. l

Said yoke 135 is secured to said rod 132 in such a manner that there is no possibility of relative movement in an axial direction along said rod 132, so that when the roller bearing 137 en gages the end surface of member 21, the only movement possible for said yoke is in a horizontal plane, carrying with it the rods'132, either in a left hand direction with respect to Figure 3 or a right hand direction with respect to Figure 4. To insure that no undue stress will be applied to rod 132 when roller 137 impinges plate 21, a bracket 138 is secured to body 116 by screws 139, the top surface 140 of said bracket forming bearing surface for the yoke 135 to slide along. y

Intermediate. the main member 116 and said yoke 135 is an adjustment member 141 which acts as a stop to determine the left hand movementof said rod 132 in respect paper lining with lieadbands.

to Figure 4 under the urging of said Vcoil spring 134. This stop 141 may be'adjusted to compensate for dierent sizes of books or for other purposes as is required.

Disposed upon said shaft 132 and secured thereto by suit-able'iastening means, a screw in this instance, and generally equidistantly spaced apart are a plurality of suction cups 143. These are shown in detail in Figures 9, and 11. Each comp 1ises a main body section 144 which is adapted to surround the rod 132. From this projects a lug or sleeve 145 through which a fastening member or machine screw 146 passes, the tightening of said screw 146 upon said rod 132 fixing the position which said suction member 143 will occupy on said rod. This, of course, must be regulated with respect to the openings 129 and the anticipated movement of members 143 therein. The main body 144 of said suction member 143 comprises a tubular portion or perforate body 14.7 which extends upwardly opening to form a flaring orifice 148, and terminatingy below in an elbow 149, said elbow 149 and upper portion 142T forming a continuous tube through which a vacuum may be appliedto anything which rests upon the plate 130 forming apart of the top of said main member 116. 4 s shown inFigure 6, the mainv member 116 may comprise a plurality of hollowed out sections instead of one large open section, but either structure may be employed withequal facility. 1n a struct-ure shown like Figure 6, where the `entire body of the main member is not open, the suction meinbers143 are disposed upon the rod 132 in suoli a position that these members do not impiiige the walls of theV main member 116 and the kflanged tops 143 do not engage the rectangular 'openings 129 best shown in Figure 3. vWhen the suction cups 143 are properly disposed, the rod 132 may be moved 'against the force of the spring 134 and within certain limits, to move the plurality of suction cups 143 dispos-ed thereon a required distance to the left in Figure 3 or to the right in Figure 4 toi' purposes of procuring proper registration or" one of the sections shown in Figures and 3 with a group ot signatures 24 in a holder 20.

When the traveling clamp train comes to a stop, one of the carriers is disposed abofe the member 116, and immediately thereafter the cani 121 engaging the lever 123 v'ns to push the main body upwardly. .it th. s time, there is disposed over the knife and plate 130, a predetermined length or portion of the Sumion is applied through tlie suction members 143 just reierred to justat the moment the mex 116 begins to rise so that the paper with headband thereon will beheld am displacement upon the top surface ci said main member 116.

is said main member 116 rises under the influence ci said above referred to cam 121, a predetermined section or width of said paper lining` with headband is sheared by the blades 114 and 115. The s ction continues. VElie main member 116 cont es to rise in the direction o: group ci signatures 24 in lie ieXible hold tiiiues the ro. er 1J contacts the rounded end et the outer plate 21 said tien" 1e holder 20.

Such end is always a predetermined dissnce from the group or natures 24 con- .ined therein, for such group ot signatures i c i act "ist the guide pin 23 tornisuoli flexible holder. irrespecthe inaccuracies of the positioning ot ber 2O above member 116 when stopped, :herod 132 will be moved by the interaction ot yolie and tace plate 21 to compensate i irregularity or inaccuracy cai 3h it t ie detached section A is end the headband.

As the main me; v 116 continues to rise, the suction continuing, said bearing 13T rolls alo-ng the vertical edge of said binder plate 21, stopping at a predetermined point when said detached paper and headband are positioned upon the roup of signatures. The glue on the latter is suiiicieut to hole the paper and lieaflbands in position, and these parts become adhesiveliT appli-ed to the group ot signatures further iourney in the boolbinding machine.

illhen the roller 1; ceased to have gagement with said plate 21, the rod 132 was urged into its normal position by the spring 134, and said rod 132 returned to the position regulated by the adjusting screw 141 shown at the right hand side ot Figure 4 and at the lett hand side ot `Figure 6.

is is shown in Figure 2 and better illustrated in Figures 3 and 4, rigidly associated with the body 116 is distributor or head out oi: which projects a plurality of nipples 151. Vintermediate said.- ',pples 151 and the nipple or elbow 149 shown upon the suction members 143, is a flexible tubing 152, so that the valves arrK with the suction line to s .id head control all individual suction members 143 one time, without requiring a plurality of individual control members for each of said suction members The dexible tubing 152 permits of the'movements oi member 132 carrying with it suction cups 143 relative to member 116 without breaking the suction line.

i suoli main member con# 12?, drops to inged in association Vthe latter reciprocates vertically..

To cause suction to be applied to the cups 143 at the proper time and such suction term nated when the lining with headbands is an lied to the group orsi-@natures 24 an* L. f3 1 C: 7 suitable valve mav be employed in suction line 154, such valves being indicated 15o. It 1s o erated bw a suitable cam driven b :y shaft 122 and intermediate said cam and shaft 19.2 is a suitable lmlr, these parts bein@r shown more or less .schematicall i,

In assoc ation with tne bed 61 a bloiv n e V158 may be arranged. This is useful to direct a continuous or broken iiow of air upon the paper lining with headbands, While the glue is drying thereon. The air therefor may come from the exhaust of the pump for obtaining the suction through cups 143 cr be supplied by an independent pump or blower. The air so directed hastens the drying of the glue when atmosphere conditions tend to retard the rapid drying thereof.

The flaring end lil-8 of the suction members, instead of being integral With said members, may be a rubber bell which is rictionally or otherwise secured to said suction members.

143 and which provides a continuation of the passage 147. Such form of device is shown in Figure 1B wherein there is disclosed a suction member lll-3 having a nipple or small sleeve extension 159 over which a iiexible or soft rubber bell or cup 160 is sea-ted to provide the part of the holder engaging the liner with the headbands attached thereto.
